Re: [Numpy-discussion] Best fit linear piecewise function?

Multivariate Adaptive Regression Splines might fit the bill? Implemented

Somethin like what is described in this article:

At a glance, that looked just hard enough to code up that I'm hoping 
someone has already done it :-)

That looks massively more complex than I was thinking for my use case. And
it seems to be a fit, rather than exactly matching a subset of points. but
as I think about it, for my use case, it might actually work well.

I'll give it a try -- thanks!
